Europeans drawn from three ancient “tribes”“The modern European gene pool was formed when three ancient populations mixed within the last 7,000 years, Nature journal reports. Blue-eyed, swarthy hunters mingled with brown-eyed, pale skinned farmers as the latter swept into Europe from the Near East. But another, mysterious population with Siberian affinities also contributed to the genetic landscape of the continent.” – see also: Before Slavery“From what I can see so far, it looks as the invaders killed all the LBK-descended farmers in northern Europe, or nearly so. The locals had had long trapezoidal houses clustered in small villages: the Corded Ware culture has almost no buildings at all, and a lot less agriculture. They didn’t make the EEF guys serfs and get a cut of their grain – the villages disappeared. They didn’t tax them, but then money and bureaucracy hadn’t been invented yet. Same for slavery: hadn’t been invented, probably. Judging from the mtDNA patterns, they didn’t even grab many of the nubile women. The genetic mix changes little as you move across the north European plain: if the invaders were picking up local genes as they rolled along, it should have. We used to call Corded Ware the Battle-Axe culture, but that’s too accurate for comfort.” – from greg cochran.

They weren’t wimps: how modern humans, like Neanderthals, braved the northern cold“Recent finds at Willendorf in Austria reveal that modern humans were living in cool steppe-like conditions some 43,500 years ago – and that their presence overlapped with that of Neanderthals for far longer than we thought.” – h/t mr. robert ford!

Stone Age groups made similar toolmaking breakthroughs“Different palaeolithic populations around the world might have developed a crucial toolmaking skill independently. This conclusion, based on the analysis of hundreds of artefacts from a recently excavated archaeological site in Armenia, weakens a long-held theory that Stone Age people in Eurasia learnt sophisticated techniques from migrating African tribes. The work is published in Science.”

Human paternal and maternal demographic histories: insights from high-resolution Y chromosome and mtDNA sequences“Comparisons of maternally-inherited mitochondrial DNA (mtDNA) and paternally-inherited non-recombining Y chromosome (NRY) variation have provided important insights into the impact of sex-biased processes (such as migration, residence pattern, and so on) on human genetic variation…. Our results confirm the controversial assertion that genetic differences between human populations on a global scale are bigger for the NRY than for mtDNA, although the differences are not as large as previously suggested. More importantly, we find substantial regional variation in patterns of mtDNA *versus* NRY variation.” – h/t juan fernández lópez! – see also: New analysis of human genetic history reveals female dominance – (heh. that was a nice twist on the story!

Admixture in Latin America: Geographic Structure, Phenotypic Diversity and Self-Perception of Ancestry Based on 7,342 Individuals“We estimated individual ancestry proportions in a sample of 7,342 subjects ascertained in five countries (Brazil, Chile, Colombia, México and Perú). These individuals were also characterized for a range of physical appearance traits and for self-perception of ancestry. The geographic distribution of admixture proportions in this sample reveals extensive population structure, illustrating the continuing impact of demographic history on the genetic diversity of Latin America. Significant ancestry effects were detected for most phenotypes studied. However, ancestry generally explains only a modest proportion of total phenotypic variation. Genetically estimated and self-perceived ancestry correlate significantly, but certain physical attributes have a strong impact on self-perception and bias self-perception of ancestry relative to genetically estimated ancestry.” – see also razib: The Phenotypic and the Genotypic.

Ashkenazi Jewish population has distinctive, yet similar genomes“Post-population bottleneck, descendants of Eastern European Jews are all 30th-ish cousins…. Compared to genomes of modern Europeans—in this case, the genomes of 26 Flemish people—the Ashkenazi genomes have 47 percent more novel DNA differences per genome. These DNA variants, while novel, are population specific; sequence sharing, where two individuals have a set of the same variants, is eight percent more abundant among the Ashkenazi Jews than it is between the two populations or even among the Flemish genomes.” – h/t billare!

The hereditarian hypothesis almost certainly true“Surely, there are huge benefits to being the first author to publish a study that almost conclusively disproves the genetic model for AA’s. Researchers with access to the data have a strong incitement to publish such a study. If the data supports the view, they have all the necessary means too. Since they haven’t published it, we can hence infer that the data does not support the politically favorable non-genetic conclusion, but instead the genetic model.” – also from emil kirkegaard.

A study of the performance of Egyptian college students on the Advanced Progressive Matrices“The Egyptian raw scores were transformed to British IQ equivalents using the published 1992 British norms for the APM, on which the sample obtained a British IQ of 89.5.

Male students obtained a non-significantly higher average IQ than female students 1.2 IQ points. Male students had greater variability than the female students.” – h/t erwin schmidt!

Human preferences for sexually dimorphic faces may be evolutionarily novel [pdf] – “A large literature proposes that preferences for exaggerated sex typicality in human faces (masculinity/femininity) reflect a long evolutionary history of sexual and social selection. This proposal implies that dimorphism was important to judgments of attractiveness and personality in ancestral environments. It is difficult to evaluate, however, because most available data come from large-scale, industrialized, urban populations. Here, we report the results for 12 populations with very diverse levels of economic development. Surprisingly, preferences for exaggerated sex-specific traits are only found in the novel, highly developed environments. Similarly, perceptions that masculine males look aggressive increase strongly with development and, specifically, urbanization.” – h/t jayman!

Do your genes skew how you taste alcohol?“A new study shows that how people perceive and taste alcohol varies as a result of genetics. The scientists focused on three chemosensory genes—two bitter-taste receptor genes known as TAS2R13 and TAS2R38 and a burn receptor gene, TRPV1. The research is the first to consider whether variation in the burn receptor gene might influence alcohol sensations, which has not previously been linked to alcohol consumption.” – alcohol tastes gooooood!

Violent Video Games and Real-World Violence: Rhetoric Versus Data“Contrary to the claims that violent video games are linked to aggressive assaults and homicides, no evidence was found to suggest that this medium was positively related to real-world violence in the United States. Unexpectedly, many of the results were suggestive of a decrease in violent crime in response to violent video games. Possible explanations for these unforeseen findings are discussed and researchers are cautioned about generalizing the results from laboratory and correlational studies to severe forms of violent behavior.” – h/t mugwump! who tweeted some of the tables here, here, and here.

Paradox of nationalism“Nationalism as we know it arose in modern times in Europe. Other countries outside Europe just don’t seem to have the same thing, although there are exceptions, such as Japan, or maybe Turkey. And in fact, nationalism was at one time considered a part of liberalism – which is another European invention…. Other countries that don’t have the same history as Europe seem unlikely to develop that kind of nationalism. Think of Iraq, Syria, most African countries, even China: they are more given to clannishness than patriotism.” – from mr. mangan, esq.

Plant breeding, not working slaves harder, drove cotton efficiency gains in the US South – from pseudoerasmus.

Confusion Over the Biological Reality of the Human Races“[O]ne can see clearly why Wade’s argument is not racist: at the core of his argument is his claim that the tribalism of racial ethnocentrism belongs to an ancient stage of human evolution that has to be overcome to move into modern states and inclusive institutions (see Wade, 136, 173-82, 196-97).” – larry arnhart on A Troublesome Inheritance.

Yes, it’s official, men are from Mars and women from Venus, and here’s the science to prove it“In his fascinating new book the developmental biologist Lewis Wolpert argues that there is actually hard science behind many of our stereotypical gender roles.” – h/t claire lehmann!

The Woman’s Heart Attack“[M]en more typically have ‘crushing’ pain; women, nausea. That women are likelier to have early warning signs, such as unaccustomed fatigue or insomnia (unaccustomed: That’s the key word here). That we are likelier — this spooked me and kept me, for months, glued to calendars — to die within a year of a heart attack. That our symptoms can be so varied and nuanced that we feel no fear, seek no help, and possibly die — which may be why, although more men have heart attacks, a greater percentage of women die of them.”

The Evolution of Culturally-Variable Sex Differences: Men and Women Are Not Always Different, but When They Are…It Appears *Not* to Result from Patriarchy or Sex Role Socialization“[E]vidence is marshaled across 21 data sources that directly challenge this foundational assumption of social role theory. Empirically, sex differences in most psychological traits — in personality, sexuality, attitudes, emotions, behaviors, and cognitive abilities — are conspicuously *larger* in cultures with more egalitarian sex role socialization and greater sociopolitical gender equity. Even sex differences in many physical traits such as height, obesity, and blood pressure are larger in cultures with more egalitarian sex role socialization and greater sociopolitical gender equity.”

School Performance After Preterm Birth“An increased risk of poor school performance for children born preterm has been shown in many studies, but whether this increase is attributable to preterm birth per se or to other factors associated with preterm birth has not been resolved…. Preterm birth was strongly and negatively correlated with school performance. The distribution of school grades for children born at 31-33 weeks was on average 3.85 (95% confidence interval = -4.36 to -3.35) centiles lower than for children born at 40 weeks. For births at 22-24 weeks, the corresponding figure was -23.15 (-30.32 to -15.97). When taking confounders into account, the association remained. When restricting the analysis to siblings, however, the association between school performance and preterm birth after week 30 vanished completely, whereas it remained, less pronounced, for preterm birth before 30 weeks of gestation. Our study suggests that the association between school performance and preterm birth after 30 gestational weeks is attributable to factors other than preterm birth per se.”

They found that not only are extreme altruists’ brains different from a normal person’s, they’re basically the opposite of a psychopath’s in one key way – indicating that a specific brain region may play an important role in people’s ability to care for one another.” – n=39, but it’s a start!

Can the Game of Thrones option save the UK?“The situation now resembles the Union of Crowns from 1603-1707 when Scotland had its own parliament but was still under the king in Westminster, and Cameron is behaving like Charles I: making promises to his northern kingdom that affect the southern one, without regards to how the southerners feel. Just as in 1640, the greatest protests are coming from the east of England, once the stronghold of Puritanism and the parliamentary rebels and now the Ukip heartland.” – from ed west.

God, Darwin and My College Biology Class“[A] third consequence of evolutionary insights: a powerful critique of theodicy, the scholarly effort to reconcile belief in an omnipresent, omni-benevolent God with the fact of unmerited suffering. Theological answers range from claiming that suffering provides the option of free will to announcing (as in the Book of Job) that God is so great and we so insignificant that we have no right to ask. But just a smidgen of biological insight makes it clear that, although the natural world can be marvelous, it is also filled with ethical horrors: predation, parasitism, fratricide, infanticide, disease, pain, old age and death — and that suffering (like joy) is built into the nature of things. The more we know of evolution, the more unavoidable is the conclusion that living things, including human beings, are produced by a natural, totally amoral process, with no indication of a benevolent, controlling creator.” – david barash, pessimist(?).

blogging lite

don't panic

many of you may have noticed that blogging’s been a little on the light side around here for the past several weeks. unfortunately, due mostly to hbd chick clan circumstances beyond my control, blogging will remain on the light side for the next couple of months(!). probably all the way through until…*gasp*…christmas!!1! (i know! who the h*ll plans that far in advance?! i normally don’t, coming from the non-“core”-european population that i do. =P )

i’m sorry about this, but as you know, blood is thicker than virtual blogging buddies, or something like that. *sigh* but i do hate it when real life interferes with my virtual one.

this is not to say that there will be NO blogging — it’ll just be limited. maybe one post a week? and a linkfest every other week? more if time allows. (except for over the next two weeks. blogging will be on hold until close to the end of this month.)

this is also not to say that i’m not around. i am around! just won’t be able to devote much time to blogging (although you’ll prolly find me slacking off on twitter…).

also: if you’ve sent me an email in the past few weeks, and i haven’t responded to you…sorry! i haven’t forgotten about you! your email’s probably got a star next to it in my inbox now. i’ll get back to you eventually! (and the check’s in the mail, too…. (~_^) )

another also: there are some comments that some of you have left that i’ve been meaning to reply to, but i just haven’t had the time. i hope to do some “comment catch-up” toward the end of the month, too. sorry again!

that’s all for now. whatever you do, just DON’T PANIC! i’m here, just won’t be blogging a whole lot for a while. DON’T PANIC! (^_^)

happy council of agde day!

september 10, 506 — 1,508 years ago today — was the final day of the council of agde, a meeting of bishops from all over what was then the visigothic kingdom in southern france (and spain, too, obviously). the council was headed by caesarius of arles and held at the basilica of st. andrew. (don’t know on which day the council was convened — sometime in late august.) the church is still there, btw!:

agde

an interesting little sidenote is that the visigoths at the time were still arians, so this meeting of bishops really related to, and would’ve affected only, the gallo-roman population of the region. in fact, the bishops were all very much gallo-romans themselves!

anyway, the council issued numerous canons, one of which forbade marriage to first and second cousins. this is the earliest official cousin marriage ban by the church that i know of, although st. augustine of hippo (d.430) certainly discussed at length in his The City of God (early fifth century) how it would be a good thing if christians were to marry out, a theme that st. aquinas would later pick up on.

people often ask me: “so why did the church get it into its head to ban cousin marriage, hbd chick?”

i. don’t. know. (*^_^*)

as i said above, this is the earliest official ban against cousin marriage from church authorities that we know of. what possessed the gallo-roman bishops at agde to do so, i have no idea. bishop caesarius was certainly an interesting fellow though. for instance, he thought that all priests and bishops (and nuns) ought to live austere lives like monks, and he actually instituted that policy in his own disocese, so i suspect that he was one of these guys who really did want to recreate god’s kingdom here on earth as much as possible, and he seems to have practiced what he preached.

caesarius’ teacher was one julianus pomerius, and his teacher was st. augustine, so here we have a direct line from augustine — who thought that christians ought to marry out — to caesarius and his council issuing this marriage canon. the funny thing is, though, augustine’s teacher was st. ambrose (d.397) who also had some things to say about cousin marriage — in fact, it was apparently he who recommended to theodosius i (d.395) to issue a secular ban against cousin marriage in the empire (theodosius did, but it didn’t stick — theodosius ii rescinded the ban). funnily enough, ambrose, like caesarius, was also from gaul (trier), so we come nearly full circle with these connections.

i suspect that the idea of avoiding cousin marriage was somehow a roman idea which was familiar to these early, urbanized, roman (or romanized) church leaders, one which they began to utilize when they encountered all these clannish barbarians (in gaul and in north africa, for example) and, as christopher burd put it on twitter, uncivilized, inbreeding country “hicks” in general. my guess is that they were trying to come up with a way to get rid of all the clannish infighting — and their plan just happened to work MUCH better than they ever imagined.

what i don’t understand — and what i need to find out more about — is how the early medieval church functioned. how the hierarchy worked and how the issuing of rules and regulations happened.

i’ve read a little about this council of agde now, and the historians i’ve read describe it as a “national” council — their scare quotes, not mine — since, unlike one of the huge church councils such as nicaea, the bishops who attended agde were only local — just from the areas in southern france held by the visigoths. what i want to know is, were the canons issued at agde binding everywhere then, or just in southern france there? could bishops in southern italy or ireland or constantinople just say, oh h*ck, we’re not going to follow those silly canons, or were they obliged to? or did canons issued by “national” councils need to be approved by rome first? i have no idea. Further Research is RequiredTM.

if canons issued by local councils only applied locally, that might explain why cousin marriage appears to have continued for some time after 506, like among the franks, for instance, who were just a stone’s throw away in northern france (until they took over the visigothic kingdom!), but who don’t seem to have taken these cousin marriage bans seriously until something like the 700s.

we do know, though, that rome was definitely behind the cousin marriage bans by the late sixth-early seventh centuries. augustine of canterbury (d.604) was sent in 595 to convert the anglo-saxons in england by pope gregory the great. he wrote to pope gregory in a panic asking what he should do about all the cousin marriage among the anglo-saxons, to which gregory replied that the newly converted should be allowed to remain married to their cousins, but going forward, NO cousin marriage.

how and when hq back in rome began backing this idea remains to be discovered.

anyway…happy council of agde day to you all! (^_^)

staffan vs. steven

pinker, that is. staffan wins, of course! (^_^)

if you haven’t read staffan’s latest post, you really should! it’s terrific!: The Myth of the Expanding Circle or You Can’t Learn How to Be an English Vegetarian.

here’s a short excerpt:

“[Goldstien] argues that it was Enlightenment (aka the Age of Reason), beginning from late 1600s, that expanded the circle of empathy, a process driven by the thinkers of that era,

“‘…if you look at the history of moral progress, you can trace a direct pathway from reasoned arguments to changes in the way that we actually feel. Time and again, a thinker would lay out an argument as to why some practice was indefensible, irrational, inconsistent with values already held.’

“We wouldn’t like to be kept as slaves, we wouldn’t like this for our family or friends either, so why would we like it for foreigners? Reason compels us to widen our circle of empathy.

“She then proceeds to illustrate her point with some humanitarians like Bentham, Erasmus, John Locke, Mary Astell etc. Pinker concedes and they both reflect on how this reason-driven process will make our grandchildren think of us as barbarians given how much further their circle of empathy will reach. End of story.

“And yet at the beginning of the dialogue Pinker stated,

“‘My fellow psychologists have shown that we’re led by our bodies and our emotions and use our puny powers of reason merely to rationalize our gut feelings after the fact.’

“This of course refers to Jonathan Haidt and others whose research makes a good case for such post hoc rationalization being an important aspect of human nature. To illustrate this behavior he likens our emotions with an elephant and our reason with the rider. The elephant, being much stronger, walks about as he pleases while the helpless rider pretends that he is in complete control.

“Given this statement, it’s a bit disconcerting how easily Pinker ignores the obvious risk that their conclusion might also be post hoc rationalization. After all, two top notch academics agreeing that all you need is reason sounds a bit like two hippies agreeing that all you need is love. So is it post hoc? It definitely has some conspicuous flaws that suggest so.

“As Pinker himself pointed out back in 2002 in his book The Blank Slate, all behavioral traits are highly inheritable and change very little over the lifespan and, most importantly, they are unaffected by shared environment, such as schools, education – and humanitarian essays. But width of empathy must, by any reasonable definition, be a behavioral trait. But by their logic it would be a trait like no other, strongly affected by shared environment, even though all other traits, thus including very similar traits like ingroup loyalty and identification, aren’t. So either width of empathy isn’t a behavioral trait – which is crazy – or it is somehow a completely unique trait affected by shared environment. Either way Pinker and Goldstein have some serious splaining to do.”

ed west on how the church created the west

THIS is the best article i’ve read all week! possibly all month. in fact, it’s soooo interesting, i’m going to read it over and over again! (pretty sure i’ve got it memorized already actually…. (*^_^*) )

by ed west, The Church v the Family appeared in The Catholic Herald a couple of weeks ago:

“So why is Europe different? The answer is the Catholic Church. Christianity in our minds is linked to ‘family values’, as Right-wing politicians used to say before an imminent sex scandal, but from the beginning it was almost anti-family, and Jesus told his disciples to leave theirs. Whereas Judaism had been heavily kinship-based, Christ voiced the view that the noblest thing was to lay down one’s life for a friend – a gigantic moral leap. This universal ideal was spread by St Paul who famously stated that there would be neither Jew nor Greek, ‘for ye are all one in Christ Jesus’.

“Although both large Abrahamic faiths are universalist, western Christianity was far more jealous of rival loyalties, such as could be found in the clan, and wanted to weaken them. St Augustine of Hippo and St Thomas Aquinas both encouraged marrying out as a way of widening social ties, and in Summa Theologica Aquinas objected to cousin marriages on the grounds that they ‘prevent people widening their circle of friends’. He wrote: ‘When a man takes a wife from another family he is joined in special friendship with her relations; they are to him as his own.’

“The influence of the Church caused Europeans to be less clannish and therefore made it easier for large territorial magnates to forge nation-states.

“Another consequence was the nuclear family, which developed in the North Sea region around the turn of the millennium. It was influenced by the western European manor system of agriculture, under which peasants managed their own farms let out to them by the lord of the manor, owing him obligations of work. This encouraged adult children to move out of the family home, whereas in most cultures three generations lived together under a paterfamilias.

“With the nuclear family came a move away from group identity and towards the western concept of individual rights and liberalism. It was a revolutionary idea and in parts of the world where the clan still rules it is still an alien one.”
